string of 6 orange balls of light float in formation slowly low over open desert northwest of Barstow, CAI live 5 miles north of Hinkley, CA is wide open undeveloped Mojave Desert. Out a north window of my house I saw a string of 6 orange balls of light moving slowly horizontally in smooth floating manner just above ground level. They were evenly spaced with bright centers and paler halo of orange light around the outside. The overall shape was like a large caterpillar. They moved from west to east in front of a hill 4 miles away to the northeast. I ran for my automatic digital still camera and set it on (15 second) "video" as I did not want to give my position away by using a flash setting. I just saw the tail end of this object(s) as it turned to the north and then west, around the back of the hill. Orange light was now coming out from both the east and west sides of the hill. Then all went dark. There is a dirt road out there that leads to Superior Valley.
